All the members using the code are asked to post up images of their install and share their experience, as well as where they got the exhaust from. That's all we ask in exchange for the extra break!

The 1Addicts only coupon code to be used at check out is "Berk5," applicable to any combination of the list below. It will also apply to those combining COBB units.

Anyone that may have bought the Berk Exhaust from Speed Freaks, LLC previously that didn't get the chance to buy the Cobb, this would be retroactive as a rebate coupon when buying a COBB unit now. It's still up to their discretion, but I think they are generally lenient towards loyal customers.

Around the 2nd week in April we'll see a coupon for the BT1801-S (Muffler Delete and Downpipes). The coupon code "Berk5" will be applicable to the following list for now:

Can they apply the discount to a full downpipe back street exhaust system?

I can ask for you.

This is what they wrote back to me:

Some of those parts are not in stock unfortunately (with us or with Berk, they are in the middle of a manufacturing run and should be available in mid Feb). In this case- yes you can place an order in advance with the coupon, we will honor it and we will not charge the card until the item ships.

have the BMW Performance Exhaust on the car from pick up at dealer,,,,being a weekend warrior and open to having the exhaust louder but not obnoxious...
1)looking at this model Berk 135i Axle-Back Race Exhaust (BT1801-S)...How much louder than my performance exhaust is this setup...no other engine mods atm............
2) will this exhaust as is bolt up without any issues to my 135i if we remove the performance exhaust....i am open to having 2 exhausts if the Berk is interchangeable with the BMW Performance one.I no in/at a near future the performance exhaust will go back on...but till then why not have some fun if this will work?
3) price for this unit and any hardware needed for installation to 08559 in NJ
thanks
